Connecting the switch and the router to the same network
There is a switch (switch) and a router. How can they be connected so that both the wireless devices from the router and the wired ones from the switch are in the same local network and have access to all devices?
If you connect the switch to the router, will the router pull the load of 32 devices? I'm not sure. And if on the contrary, will the devices connected to the router from the devices connected to the switch be available?

Since the models are not specified, there are many options.
If the router is able to distribute different subnets on the LAN and on the WiFi , this should be disabled. In the case of independent configuration - for example, to form two different DHCP scopes from the same subnet (say, 192.168.0.10..100 for a wired network and 192.168.0.110..200 for wireless, mask /24). Otherwise, the segments will not see each other directly (say, in a network environment) without a WINS / DNS server. Although access by direct address indication or static matching (HOSTS) will be (the router will provide routing, because its local (e) address(a) will be (ut) default gateways for clients). However, such models/firmware are infrequent, and, as a rule, the interface immediately shows that this equipment is never for beginners.

If the router distributes the same subnet to both interfaces, there are no special settings on the clients for mutual visibility (except for enabling the necessary clients/services on the interface and configuring firewall / network category) is not required. And on the router, you need to check for the following settings (however, these settings are also rare in the firmware).
A) Broadcast routing. If there is such a setting, you should allow it. Otherwise, the segments will not "see" each other.
B) Multicast routing. If there is such a setting, you should allow it. Otherwise, some services will be unavailable.
In) Isolated networks. If there is such a setting, it should be unplug. Otherwise, not only a segment with a different transmission medium will be unavailable, but wired segments connected to different LAN ports will not be available to each other.
In terms of traffic performance, all wired clients connected to the switch, and through it to the router, share the performance of a single LAN port. In this sense, the number of customers is not important. But in terms of overflow, ARP tables and NAT tables are different clients. And for the initial router level 32 clients is too much. Even a lot...
You need to connect the switch to the lan ports of the router.
Devices that hang on the switch will not interact with each other through the router. If you connect the switch to the wan of the router, the devices will be in different networks. Devices will be available when NAT is disabled in the router
